Title: Directionally controllable night light
Inventor: COPELAND STEVE A
IPC: F21V14/02
Filed: 2006-11-10
Granted: 2014-04-29
Abstract: A night light comprising a housing with a rotatable bezel mounted thereon. The housing includes a rear wall with electric blades extending outwardly therefrom for engaging in an electrical wall outlet. The bezel is rotatable about a first pivot axis. A LED array is mounted in the bezel and the array is rotatable about a second pivot axis. The second pivot axis is oriented on a different plane to the first pivot axis and preferably lies at ninety degree thereto. When the bezel is rotated about the first pivot axis, the direction of the light emitted from the LED array is changed. Because the bezel can rotate through 360°, the LED array can be rotated through 360° about the first pivot axis. The LED array can be pivoted through an arc of between 160° and 175° about the second pivot axis. The combination of being able to rotationally adjust the position of the bezel on the housing and to adjust the position of the LED array within the bezel allows the individual to control the direction of the light emitted from the night light.

Granted: 2014-09-30
Abstract: In one embodiment, a system for data handling in a distributed communication network includes a data-handling node (DHN) residing at a mission management center (MMC). The MMC manages operations of one or more remote units. The DHN  receives a stream of data units from a routing system. The stream of data units includes both stored mission data (SMD) and telemetry data having originated at the remote units. The DHN, in near real time, extracts the telemetry data from the stream of data units, identifies one or more subsystems of the MMC for receiving the extracted telemetry data, and communicates the extracted telemetry data to the identified subsystems of the MMC for processing.

Abstract: A filter system for temporary placement of a filter in an artery or vein is disclosed. The filter system includes a guidewire that is first positioned across a lesion within a vessel. The guidewire may include a distal stop. A slideable filter is then advanced along the guidewire using an advancing mechanism, typically an elongate member slideable over the guidewire and contacting the filter. A capture sheath may be disposed about the filter during advancement. Once the filter is positioned downstream of the lesion, the capture sheath is withdrawn, allowing the filter to expand. Further distal advancement of the filter is prohibited by the stop. After expansion of the filter, the capture sheath and the advancing mechanism are withdrawn from the region of interest, and removed from the patient's vessel. The filter may then be retrieved using a capture sheath or exchanged for a second filter after removing the first filter.

Abstract: The enhanced detection of defects in the bulk dielectric material (Specimen) having radiation partly reflected at interfaces where the dielectric constant changes (e.g., where there are defects or structures). A sinusoidal or quasi~sinusoidal wave (Microwave Source) results. Localization or imaging of features is enhanced by exploiting the variation in distance resolution (Standoff+/-) in a sinusoidal or quasi-sinusoidal standing wave. At characteristic distances, the wave has a high slope and the amplitude of the wave varies strongly with small changes in distance (Standoff +/-). By inspecting at these characteristic distances (Standoff +/-), the resolution is enhanced. By systematically varying the position of the transducer or specimen, detailed images may be formed of the internal structure of the specimen across a range of depths. Defects and structures may be detected at smaller sizes than has previously been possible.

Abstract: A method and system for providing asymmetric modes of operation in multi-carrier wireless communication systems. A method may assign a long code mask (LCM) to an information channel associated with a plurality of forward link carriers to transmit data from an access network to an access terminal; and multiplex the information channel on a reverse link carrier. The information channel may include one of data source channel (DSC), data rate control (DRC) and acknowledgment (ACK) information, and the multiplexing may be code division multiplexing (CDM). The A may instruct the AT on whether to multiplex the DSC information based on feedback from the AT. The method may further offset the ACK information on the reverse link to reduce the reverse link peak to average, CDM the information channel on an I-branch and on a Q-branch, and transmit the code division multiplexed information channel on the reverse link carrier.

Title: Dynamic mixer
Inventor: KELLER WILHELM A
IPC: B01F27/906
Filed: 2006-10-03
Granted: 2014-07-08
Abstract: The dynamic mixer for mixing components in different volumetric amounts comprises a rotor housing (25) in which a mixing rotor is arranged and which is closed on the inlet side by a cover (45) on which inlets for the components are arranged. The inlet (47) for the first component having the larger volumetric amount leads to an antechamber (32) that communicates with a following mixing chamber (36) by at least one passage (19). The mixing rotor (10) includes a distributor body (13) located in the antechamber for distributing the first component around the axis of rotation of the mixing rotor. The inlet (48) for the second component having the smaller volumetric amount leads to at least one inlet opening (54) located in the area of the passage to the mixing chamber ransversally to the axis of rotation. The mixer allows to obtain the correct mixing ratio from the beginning, as well as an optimum and largely bubble-free mixture, and this is achieved at a lower feed pressure, a lower torque, and a lower temperature increase than in conventional mixers.
